4. BACKGROUND OF INVENTION

Machine Element or Mechanism/Multiple Levers (74/43)—The inventor cameup with the idea to attach a motorized jack to the seat of personalambulatory scooters after having trouble accessing hard-to-reach areasin his garden. This motorized seat jack mechanism will offer ridersvertical mobility in addition to their current distance mobility. JohnA. Anthony realized a scooter that could better mimic the movements ofthe human body would be more beneficial to those challenged with limitedmobility.

5. BRIEF SUMMARY OF INVENTION

The multiple lever mechanism improves conventional ambulatory scootersby lifting and lowering their seat to give riders verticalmaneuverability while in a stationary position. Current personalscooters on the market cause great discomfort to riders attempting toreach areas above or below them.

6. BRIEF DESCRIPTION OF SEVERAL VIEWS OF THE PHOTOGRAPHS

The four photographs allow the examiner to view the multiple leverscooter seat jack in the Extended Position—Caddy Corner where thescissor lift mechanism raises the rider to a higher plane than commonscooters at 21 inches

(FIG. 1); a Side View—Lowered Position demonstrating how the mechanismrests just 5½ inches at its lowest point

7. DETAILED DESCRIPTION/PREFERRED EMBODIMENT

Manufacturers can install the motorized seat jack in ambulatory scootersto give their product better ability to lift and lower. It rises higherand lowers beneath current scooters. The mechanism is made up of threemajor components: THE BASE UNIT, THE SCISSOR LIFT and THE SEAT REST.Each part number referenced in the “Detailed Description” below can befound marked on the photos in the “Figures of Proposed Patent” sectionon pages 10-13. The mechanism is composed of the following parts listedand operates as follows: (see next page) UNIT QTY PART DESCRIPTION MEAS.PHOTO NUM.

THE BASE UNIT is cradled in a tray (Num1—FIG. 1) that manufacturers canplace in ambulatory scooter. A 14″ screw (Num2—FIG. 1) attached to themotor (Num3—FIG. 1), is fined with a handmade nut (Num5—FIG. 1). Whenthe motor rotates the screw in reverse, the momentum pulls in the roundbar (Num4—FIG. 3) causing the SCISSOR LIFT to pivot upwards to a maximumof 21″. Slides (Num6—FIG. 1), resting in scissor lift tracks(Num7—FIG. 1) towards the rear of the mechanism stop when they hit amicro switch (Num8—FIG. 1). A second micro switch stops the slides whenthe SCISSOR LIFT lowers a minimum of 5½″ (see FIG. 2). The motormounting brackets (Num9—FIG. 4) brace the motor in place. A power cord(Num10—FIG. 4) connects to the power source in most ambulatory scooter.PHOTO UNIT QTY PART DESCRIPTION MEAS. NUM.

THE SCISSOR LIFT includes eight pieces of square tubing (Num1—FIG. 1)bolted (Num12—FIG. 2) together in four places. They're placed on eitherside of the scooter creating two accordion mechanisms. Washers(Num12—FIG. 1) and nuts (Num14—FIG. 1) are used to secure all of thebolts. On top of the unit snap rings (Num15—FIG. 1) hold two round bars(Num16—FIG. 1) in place to cradle the SEAT REST.

THE SEAT REST consist of twin square tubing (Num17—FIG. 3) facing frontto back. In the rear (Num17—FIG. 4), they're welded on top of anothersquare tube (Num18—FIG. 4) that's facing side-side. One of the roundbars on the SCISSOR LIFT rests inside the squared tubing to allow freerotation as the SCISSOR LIFT rises/lowers. Tubing slides (Num19—FIG. 2)are fitted around each piece of twin square tubing which allows them tomove freely as the SCISSOR LIFT rises/lowers. The round bar from thescissor lift runs through the twin square tubing to allow rotationduring the lifting and lower of the jack. The placement of the tubingand bars creates a “tic-tac-toe” shape to hold up a scooter seat (seeFIG. 1). A steel plate (Num19—FIG. 1) is welded to the center of the“tic-tac-toe” shape and a hollow steel seat stump (Num20—FIG. 3) iswelded to the center of the plate to fit into a hole in the bottom ofthe scooter seat. The stump has three notches to allow the seat to restin three directions: front, left and right (see FIG. 3).

1. The Motorized Seat Jack for Ambulatory Scooters lifts its rider higher than any other scooter.
 2. The Motorized Seat Jack for Ambulatory Scooters lowers the rider beneath all current scooters.
 3. The Motorized Seat Jack for Ambulatory Scooters allows riders to mount and dismount their seat at a level more appropriate to their individual height.
